Old ldiskfs MDT's that contain a single OI container named "oi.16"
trigger an automatic OI scrub on each restart.  This is because
osd_oi_table_open() gets ENOENT opening "oi.16.0" and consequently
sets bit 0 in scrub_file::sf_oi_bitmap.  This bit indicates the OI
container 0 needs to be recreated, and it triggers a scrub in
osd_fid_lookup() for lookups that fail with ENOENT.  Fix this by
clearing the bit in osd_oi_init() after a successful open of
